PHYS.Org: A source of extremely high-energy particles in the Milky Way identified

Shielding astronauts from the killer radiation they face is a central challenge facing any designer of a deep-space crewed mission. Even relatively low levels of exposure for long periods of time can lead to everything from central nervous system damage to cancer. But current solutions, such as passive water shells or active superconducting magnets, have…

After nearly 40 years of research, scientists have uncovered evidence that challenges a long held assumption about forest soils. The world’s longest running soil warming experiment suggests that even carbon once considered stable can begin to break down as temperatures rise, releasing additional CO2 into the atmosphere. Jerry Melillo, a Distinguished Scientist at the Marine…

I've been building a full turbulence course on YouTube and hit the point where the algebra gets unreadable without index notation. This video is a standalone introduction to the Einstein summation convention, free vs. dummy indices, and the Kronecker delta, using the Navier-Stokes equations as the worked example throughout. Even outside fluid mechanics, if you've…

Welcome to the International Space Station! | Photo Credit: Flickr In low Earth orbit can be found the International Space Station — a large laboratory where astronauts from different countries live and work together while circling Earth every 90 minutes. What began as a project involving the United States, Russia, Europe, Japan, and Canada is…

A meteorite that streaked over New York City and crashed into a New Jersey rooftop came from an asteroid that once had briny water beneath its surface. The rock may have a similar composition to those that brought water and organic materials to early Earth, researchers report July 15 in Science Advances. The meteorite lit…
